  • Patent number: 11951587
    Abstract: The present disclosure is directed to techniques of zone-based target control in chemical mechanical polishing of wafers. Multiple zones are identified on a surface of a wafer. The CMP target is achieved on each zone in a sequence of CMP processes. Each CMP process in the sequence achieves the CMP target for only one zone, using a CMP process selective to other zones.

  • Publication number: 20230198849
    Abstract: A topology path obtaining method of a mesh network and a system configured to obtain a topology path of the mesh network are provided. In the method, a topology query packet transmitting step is performed to configure a root access point to transmit a topology query packet to a plurality of extended access points. A topology response packet transmitting step is performed to configure each of the extended access points to transmit a first topology response packet to the root access point according to the topology query packet. A topology path generating step is performed to configure the root access point to collect and process a plurality of the first topology response packets and a second topology response packet to generate the topology path. The topology path includes a connection relationship between at least one client device and one of the root access point and the extended access points.

  • Patent number: 11493977
    Abstract: An electronic device includes a processor, a battery, a charging circuit, a controller, and an arithmetic logic unit. The processor is capable of operating at a preset frequency or a low frequency. The charging circuit is electrically connected to an external power supply and a battery and transmits a disconnection signal and to be powered by the battery when the external power supply and the charging circuit are changed from a connected state to a disconnected state. The controller is configured to transmit a first control signal when the external power supply and the charging circuit are changed from the connected state to the disconnected state. The arithmetic logic unit is configured to transmit a frequency reduction signal to the processor according to the disconnection signal and the first control signal, so that the processor reduces the preset frequency to the low frequency and operates at the low frequency.

  • Patent number: 10772154
    Abstract: A method for generating a prompt message for network connection conversion and a network system thereof are provided. The system can be a LAN with multiple access points (APs). The method is operated in a root AP. The root AP receives a connection conversion command from a user device, in which a target AP is designated. The root AP determines at least one AP that is available to be connected with the target AP based on an instant wireless signal strength there-between. After that, the target AP obtains at least one connection rates from the target AP to the root AP via the at least one available APs. The root AP generates a prompt message for connection conversion according to the connection rates. A topology map displayed on the user device can be used to indicate the available APs for the connection conversion.
